Running split flower rooms is pretty much impossible if you have a day job. I understand why, because you only have so many amps available to the room but a ton of space. I have that problem too. But just to warn you it can be demanding you need even canopy tops for sure.
You need to get in front of the demands of the flowering room and actually seeds are the best thing right now. (This from the clone guy).. Seeds will pop when we need them to and you need to get rolling so it makes it easy, it's what I did, it's what your daddy did. So let's just make up some numbers and go through this.
4x4 = 4 plants of the type we want to flower and for this example they need approximately a 2 months veg. So that's 16 plants every two months.
1. Germinate/Plant 16 plants right now and scramble to get your room up. (First run will not be fully vegged when we flip, let's get some smoke going)
2. About a week before flip take cuttings from veg so we can learn cloning, clean up the bottoms stalks and wait 1 week. (No more than 1/5th of the entire foliage should be removed)
3. Germinate your next set of 16 seeds we will be flipping to flower in 1 week now. (Hope they all pop although not likely)
3. Flip the first 16 plants after a week now plant 16 more seeds. (We can't count on clones yet)
4. You will likely be less than 16 seeds germinated but also > 2 months in flower so it will kind of work out. But basically just repeat here.
Now we need to learn cloning we need to know how long does it take to get them rooted, how long before the roots take to soil and how long it will be before they are the size of a 2 month old veg plant. Clones root at different rates so I run 3 cloners to get 18 plants. When you learn cloning and become intimate with your flag ship strain you will have a flag ship strain that is the same every time. Genetic drift happens to other people not us so don't worry
P.S.: I used 2 months as the example because that's what I use for my slow grower you may need less veg or more depending on whatever
